1 Claim. (Cl. 299-90) This invention relates to a shaving brushconstruction.

It is an object of this invention to provide a shaving brushconstruction with a dispensing handle adapted to contain the soapsolution and which can be squeezed to elfect a discharge of the soapsolution to the brush bristles and wherein the reservoir serves as thehandle for the brush.

Other objects of the invention are to provide a shaving brush structurewith a removable head having bristles and serving as a cap for thereservoir which is of simple construction, inexpensive to manufacture,has a minimum number of parts, light in weight, compact, sanitary andelficient in use.

For a better understanding of the invention, reference may be had to thefollowing detailed description taken in connection with the accompanyingdrawing, in which:

Fig. l is a perspective view of the brush structure embodying thefeatures of the present invention and surrounded by a container in whichthe same is disposed when not in use.

Fig. 2 is a longitudinal sectional view of the brush structure.

Fig. 3 is a perspective view of one of the check valve elements.

Fig. 4 is an elevational view of the structure with the top portionbroken away to show the position of the check valve element mounted onthe top thereof.

Fig. 5 is an elevational view of the brush structure showing a checkvalve element in the bottom of the reservoir.

Fig. 6 is a perspective view of the wire which is disposed in the upwardend of the tube to diifuse the upward flow of the soap solution, leavingthe reservoir and to distribute it to all sides of the brush bristles.

Referring now to the figures, 10 represents a handle reservoir formed offlexible plastic and of the nature of a squeeze bottle, now commonly inuse and having a neck 11 that is threaded to receive a cap 12 thatcarries a brush structure 13. This brush structure includes forwardlyextending bristles 14. The brush structure is threaded upon the neck 11of the reservoir and can be easily removed to refill the reservoir withthe soap solution. In the top of the reservoir there is provided a checkvalve element 15 that will permit the insertion of air into thereservoir. A similar check valve element 16 can be provided in thebottom of the reservoir.

These check valve elements are shown in Fig. 3 to include a rounded topshaped formation closed at its end to provide cross slits 17 and aflange 18. Air will pass downwardly into the top shaped formation of theelement and through the slits as the pressure on the sides of thereservoir is released. Upon applying pressure, for prac tical purposesno liquid can. escape. A long tube 19 is fixed within the opening in theneck portion 11 and extends downwardly into the bottle and to the bottomthereof. This tube extends also upwardly through a bore 26 in the brushstructure. A wire element 21 is disposed in the upper end of the tube 19in order that the liquid as it is projected from the tube will bedistributed well within an opening 22 in the brush bristles 14 todistribute it upon all sides thereof. Upon applying the brush to theface, the lather will form thereon. It will be seen that there has beenprovided a reservoir that serves as a handle for the brush. The brushstructure is detachable from the reservoir or handle. The reservoir canbe used again and refilled or it can be made sufl'iciently cheap so thatit can be thrown away when the contents thereof have been spent.

The brush structure is made of the conventional badger, of nylon or cowhair.

The tube 19 is of semi-flexible plastic and extends the entire length ofthe reservoir. It tightly fits within the opening within the brush base13.

If the reservoir is delivered without the brush structure, an extra capcan be provided and the tube 19 can be made a part of the brushstructure.

The reservoir is pierced at various places for receiving the tightfitting check valve elements 15and 16. There may be one or several ofthese elements in the reservoir and they may be disposed in the basealone, as shown in Fig. 5, or any place around the neck, as shown inFig. 4, and as indicated at 15. There may be a series of such elementsaround the neck or around the bottom.

The reservoir contains a fluid soap solution which can lather rapidly.It is delivered to the brush bristles by lightly pressing in on thesides of the reservoir. The reservoir immediately regains its shape bythe action of the check valve elements, which suck air in when pressureon the reservoir is released. Without these valve elements, thereservoir could not regain its former shape because of the extremelyhigh viscosity of the soap solution, which acts as a barrier to theintake of air through the tube 19 and moreover mats the bristles aroundthe upper end of the tube 19 so that at times air intake is impossible.The wire loop pin 21 has a double action in that it forks the soapstream and delivers it to each side of the brush and it acts as a ballvalve preventing any spilling of the solution regardless of the positionof the brush, and its combined reservoir.

It is to be understood that the check valve elements 15 and 16 may bemade from rubber, synthetic rubber or any other desirable material.

When shaving, the brush is first moistened in Water. The soap solutionis then delivered to the tip of the brush as above described, and thenthe dry beard is lathered. For sanitary purposes a container 23 having ascrew perforated cover 24 may be provided. When the brush is not in use,it can be kept in this container.

While various changes may be made in the detail construction, it shallbe understood that such changes shall be within the spirit and scope ofthe present invention as defined by the appended claim.

What is claimed is:

A lather foam dispenser for use with a brush including the combinationof a flexible reservoir having a threaded neck at one end thereof withan outlet port therethrough providing an outlet for said reservoir, anelongated flexible tube extending inwards through said port in said neckinto the reservoir, a cap with an internal thread fitting upon thethreaded neck, said cap having an opening registering with the outletport of said neck for receiving the outer end of said flexible tubetherethrough so that said outer end opens to the surface of said cap,and a check valve in an end wall of said flexible reservoir, a shortwire loop having the engaging ends twisted relative to each other, saidengaging ends being disposed in the outer end of said tube and the loopportion extending a short distance from the end beyond the outer end ofthe said cap.
